Brassyblonde, I am not saying that individual type 1s cannot achieve non diabetic levels, I am saying not all of us can or wish to by risking hypos which can be deadly. Please try to understand, when some of us get into the 4's by use of insulin, the danger is that it is so very easy to slip down into the 3s and even 2s. So many other factors come into it, what we are doing, whether we have eaten, what's going on at work, whether we have exercised, whether our basal is suddenly going to kick in at that exact moment, whether we are ill or coming down with something and that's before we even get to having to be above 5 for driving. You say it is not 'PC', but come on, would YOU want to take a risk of dropping to the floor at any given moment and being carted off in an ambulance, would YOU want to be at work or shopping and feeling the constant tremors and shakes that accompany being in the low 4s? It would be lovely to be able to do this and I envy you for your great numbers but I simply cannot get constantly below 6 without all of the above happening. I shall simply have to sit at around 6 and hope for the best but at least I will be able to actually leave the house without worrying about falling in to the road.
